Harry Avery’s Castle is located in a field in County Tyrone, Northern Ireland, south of the town of Newtownstewart.

A local lord of the O’Neill clan is supposed to have erected Harry Avery’s Castle in 1320. The castle is named after a native leader named Harry Avery, who died in 1392.

The castle was a two-story rectangular structure with the remaining huge D-shaped twin towers protruding from the south face of an artificially scarped hill with its sides revetted by a wall to form a polygonal enclosure. This two-story tower building would have served as a tower house, and many timber buildings would have been housed within the enclosure.

In 1609, the English seized the fortress. It was thereafter utilised as a quarry for construction materials.

If you leave the grazing livestock alone, you can visit Harry Avery’s Castle for free. Despite the fact that there isn’t much left of this castle, tourists like it, particularly because of its deserted setting with spectacular views of the surrounding countryside and the Derg Valley.
